nRF52 - TWI and BLE

[Levi]

Hello,

I would like to collect sensor data over TWI and transmit to a smartphone using BLE. I am wondering what the best way to do this would be. I am using SDK 12.2.

So far, I have one sensor working using TWI. My goal is to get all sensors working first, and then work on the BLE part. My problem is that there aren't any examples that use TWI and BLE together in the SDK. Does anyone have any suggestions or examples or tips for me?

Thank you!

There is no magic to this.

Your TWI code should work when integrated with BLE

I'd recommend you start by copying the ble application template, then look at adding a custom service (or one of the example services, to the template, and finally intergate your TWI code when you need to read the sensors

Precisely what services you use and whether you collect data from your sensors before or during the BLE connection is specific to your use case.

Hi Roger, this will give me a good starting point for my project. Thank you!
